"I'm disappointed that Forever 21 [because I felt] like they didn't have to ask permission to use my lyrics in their commercial product, but I'm also flattered at the same time," Choi said when it was brought to his attention. (Check out the video of the song after the jump.)

What the Audrey Magazine post didn't mention is that this shirt doesn't just lift lyrics from Choi's song, it also printed lyrics from various John Mayer songs: "Daughters," "Your Body is a Wonderland" and "Heartbreak Warfare." We're willing to bet Forever 21 didn't ask for permission to use those lyrics either, but we sent out an inquiry to John Mayer's people asking about it anyway.

In the meantime, you can try to figure out which lyrics in Choi's "That Girl" can be found on the shirt.
